I searched and didn't find anything, so i figured i would ask. Has anyone ever done a heater line reroute where you run the heater return hose into the upper radiator hose to help cooling? They do it when they turbo miatas and i was wondering why ppl wouldnt do it to help cooling on the 7. the only reason the line runs back into the lower radiator hose is to help warm up from what i understand.


So anybody done it?

anyone have any opinions on it?
